The name refers to the construction of the drainfield.
A conventional septic system is typically installed at a single family home or small business.
With this design effluent is piped from the septic tank to a shallow underground trench of stone or gravel.
This system uses a standard septic tank but instead of the conventional pipe leach field the leach field is made of interlocking polyethylene arches that provide a continuous drainage area.
Here is an explanation of a sand filter septic system.

Septic mound system design.
The effluent flows from the house to perforated pipes within a layer of gravel filled trenches.
If you prefer.
The effluent seeps into the gravel from the perforated pipes and then the soil.
The gravel stone drainfield is a design that has existed for decades.
As a result they are one of the best septic system alternatives.
Septic system alternative designs refers to any onsite wastewater disposal method other than the widely used conventional septic tank and leach field.
